Hi Jonathan,
That really depends on what you mean by "support".
They will all open a g711 chanel that you can send a fax or modem call over.
But if you want to do fax  or modem "relay" things change.

Take a look at

For fax support.
If you want fax relay you should also take a look at the new sg3 support

For modem relay see

Brian

Hello,


I need to know the answer to these questions. Which device supports
analog MODEM and FAX? ATA, FXS or VG224?

I have read that ATA does not support modem. Does FXS and VG224 supports
MODEM?


Thanks
Jonathan
